Be it known that lf, ALBERT All Knnnoee,

a resident of Kansas'City, in= they county" of Jackson4 and yState ofMissouri, acitiz'en of 5 the UnitedStates, have invented certain new anduseful- Improvementsl in Chemical Fire-Extinguishers, `of which thefollowing isa' specification; 1

- My'inv'entionf relates to improvementsi-n chemical fire extinguishersparticularly'c'onstr uctedf and adapted for"` service in' oiiicebuildings, warehouses, apartments, vesselsV operate tof immediatelyextinguishvthe/fire without damage' to any'othe'r local-ity' thanv wherethe fire originates.v

26 Another object of my invention-is the provision ofa chemi'calfirevvextinguisher which will operate instantly to! extinguish the fire, andwhich `will insurethe proper mixture of chemicals with the Water toproduce the most elicientl fire extinguishing flu-ida `Another objectofinventi'on isthe provi-si'on of achemical fire extinguisher which willbe automatic, instant and practical in operation; which' will belcomposed of compara-tively few part-s to insu-re simplicity, durabilityandi cheapness of construction; which' willv be coin-pactl and small in@size to occupy a smal-l space;` and. which generally in every particularwill be efficient, reliable f andpractical.`

'With these objects inv view, ymy invention consists of a chemical fireextinguisher' em` bodvlng novel features of construction and l comination 'of parts, Substantiallyas-,dis-

of the apparatus which come within the scope of the claims.

tages and features ofv merit be appreciated,

I have shownin the accompanying` draw-l ings'a chemical 'fireextinguisher constructclosed herein',` it beingr'understood that any cchangesv may be made 1n the construction.

Inf order that thev construction' indeta-il. and the .operation of myextinguisher may be fully understood and its@ many advaned according to:the best lprinciples I have so7 far devised', and in' said drawings: w

Fig. 5 represents a 'sectional view onf-the -which thevl safme numeralsofv reference are v used to denote similar parts inail/the views: Thenumeral Vl designa-tes a platform or base upon which the entiremechanismconiprising myfchem-ical firey extinguisher is'supported and which is ofthe desiredlvsize according to. the capacity of the machine, and upoirthis base is) secured the motor 2,1 upon whose shaft 3l, is'mountedV a'drivin-g gear wheel 1.1,"whichI meshes with the large' gear vwheel 5onthe shaft 6,; ofthe pump`.7, which isconnected wi-thfthe deliverypipeiS, which. directs the .mixed chemically charged liquid tothe pumpfforthe purposes-of discharging fires In use thel motor is connected? incircuit witlra sprinkling systemA vof any desi-'red character operatedelectrically, and instantly upon the fire occi'irring at anyplace in'the sprinikle'rsystem-l the 'circuit will be closed whichfwilfl* operatethe motor fto drive f the pump andi force they extinguishing liquidthrough thefpifpe tothe proper4 point, as'will bereadilly understood.-

l Mounted' upon the 'base'r or' platform and in parallel relation'to themotor and. pum

is the-'supporting structure or' framework 9,v which rises froml thesupplyta-nk or con- I tainer 10 which.A is of the desired size and' saidcharged lliquidffor extinguishing the is connected to the delivery pipeby means of the branch pipe 11, in which is located the rotary valveI12, the operation of which Will presently appear, and arranged above thesupply tank and supported upon the frame are the chemical containers 13and branch pipes 16 and 1.6', thus in a manner to be described, feedingthe chemical from the pair of tanks directly into the supply tank, Whereit mixes with the Water therein to provide the chemical Huid forextinguishing the fire.

The discharge pipes or branches are provided, the pipe 16 with thecouplings 17, iu which are seated the rotary valves 18, yWhile the pipe16 is provided with seats 19, for the gate or slide valves 20, thevalves being operated by a novel mechanism which I Will new describe.

The shaft of the motor carries a small gear Wheel 21, Which meshes withthe gear Wheel 22, operating a train of gearing consisting of gear Wheel23, which meshes and drives gear Wheel 24, which drives gear Wheel 25,all on the series of studs mounted in the inclined bar or frame 28, andthe rotation of gear Wheel 25, meshing with gear Wheel 26, connected topin 29, engaging slot 30, in pivoted lever 31, oscillates said lever,causing the upper slotted end 32 thereof, to engage the pin 33, carriedby the depending arm 34, of the yoke 35, to reciprocate said yoke, inits guides 36, said yoke carrying lateral pins 37, Which move slottedarms 38, on the pair of rotary valves 18, to open one valve and closethe other simultaneously, as shown in Fig. 3, and said yoke is furtherprovided with vertical pins 39, which engage slotted levers 40, on thevalves 20, to open one and close the other of said valves, the upper ofsaid valves 20, being provided with aseries of arms 41, Which provide anagitator for assisting in the proper stirring or mixing ofthe chemical.

From thisconstruction it will. be noted that motion is transmitted fromthe gear Wheel on the motor shaft to thc train of gearing, and lliat thelever associated with said train of gearing is given a reciprocating orrocking action, the effect of which is to move the yoke back and forthin a horizon- ',tal direction and simultaneously open and close onerotary valve and one slide valve, of the chemical supply tanks, thepurpose of which is to discharge at regular intervals the necessary anddetermined amount of chemicals into the Water of the supply tank,

which is provided with the inlet controlled by the oat valve 42, whichpermits the water to flow into the tank., and to automa ti cally operatethe controlling valve of the inlet pipe, I provide the lever 43, whichis connected to the valve at 44, and from which leads the rod or pitman45, tothe pivoted lever 46, which is engaged upon the starting of themachine by the cam or eccentric 47, operated by the motor through thetrain of gearing, to immediately move the lever and open the valve tothe position shown in dotted line.

From the foregoing description, taken in connection with the dravving,the operation of my invention will be so apparent that furtherelaboration thereof is deemed unnecessary, and it will be understoodthat the chemical tanks are properly charged with the most suitablechemical for the purpose, and that the supply tank which is incommunication with said chemical tanks is supplied With the properamount of Water, and that instantly upon the starting of the motor, thetrain of gearing is set in motion to operate the force pump andsimultaneously the valve mechanism associated with the chemical tanksand supply tanks to insure the proper supply and mixture of thechemically charged fluid and the completion of the delivery of thisfluid to the point Where the fire has started to instantly andautomatically extinguish such fire. t

In the operation ofv my 'lire extinguisher the Water under servicepressure is supplied to the inlet pipe 8 which leads to the Water supplytank 10 and the amount of Water in said tank is regulated by the floatvalve, as shown most clearly in Fig. 3, to retainat all times the fullamount of Water necessary for supply through the feed pipe 48, leadingfrom the tank to the pump 7, and leading from the pump 7 is thedischarge or outlet pipe 49, which pipe is preferably connected to thesprinkling system of any character, and instantly upon the starting ofthe motor the Water is pumped from the pump through the discharge oroutlet pipe to the place Where the lire has started, as Will be clearlyunderstood by reference to the drawings and description.

I claim:

1. A chemical iii-e extinguisher, consisting of chemical supply means, amixing Afluid means associated with said ':lieinical supply means, avalve mechanism for controlling the supply from the chemical supply tothe mixing fluid means, and automatically operated mechanism forcontrolling said valve mechanism, said valve mechanism consisting of twosets of valves, operated one to open and the other to close, meanscarried by said valves to operate them, and means for operating saidmeans simultaneously.

2. A chemical fire extinguisher, consisting of a motor, a pumpassociated With and operated by said motor, a Water supply tank, aninlet pipe .leading to said tank, a valve mechanism controlling saidinlet pipe and operated by said motor, chemical supply tanks associatedwith said water supply tank and discharging thereinto, a valve mechanismfor controlling the discharge from the cheinical tanks to saidWater-supply tank and operated from said motor. l p

A chemical lire extinguisher, consisting of a water tank or container,an inlet pipe connected With said container, a controlling valve forsaid inlet pipe, a controlling valve for said container, .a pump incommunication with said container7 a discharge leading `from said pump,a motor for operating said pump, chemical tanks for supplying chemicalsto said Water-container, and a Valve mechanism for controlling thesupply of chemicals to said container and operated 'from said motor,said Valve mechanism consisting of two sets of valves operated one 'toopen and the other to close, means carried by said Valve-to operatethem, and means for operating said means`simultaneously.

In testimony whereof I hereunto affix my signature.
